Description of problem:
Using the -M or --month-sort options to /bin/sort causes it to crash with failed
assertion (if run as regular user) or segfault (when run as root).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.cat foo.txt | sort -M
Actual Results: sort: sort.c:1770: getmonth_mb: Assert-makro "mblength != (-1)
&& *wpp == ((void *)0)" ei pidï¿½ paikkaansa.
Expected Results: data sorted by month code
Seems to work fine in coreutils-5.0-5. Please supply a small test case that
causes problems for you, so that I can verify the problem is really fixed.

test case that causes sort -M to fail
The bug is related to line length and locale, if the lines to be sorted are
under 49 charecters or a non-UTF-8 locale is used there is no error.
$ cat test.txt | sort -M
Feb 5 bbbb qqqqq zzzz aaaaa pppppp ggggg dddddddd
Jan 1 aaaa ccccc gggg xxxxx yyyyyy zzzzz ffffffff
$ rpm -q coreutils
$ echo $LANG
So it looks like this really is fixed.
Tim, where can we find coreutils-5.0-5?
Never mind, I was only asking to see if I could get away without
having to tinker unhooking the selinux bit.
Rebuilt 5.2.0-4 for AS3 - the selinux bit
Note that 5.2.0-4 has bugs, since 5.2.0 isn't very old. In
particular, sort -M doesn't work. :-)
Grab 5.2.0-7, which should appear tomorrow -- that has fewer bugs than
5.2.0-4, but (I'm sure) more than 5.2.0-8 will have when it exists..
